| Active Member Join Date: Feb 2007 | Converting cc to ci I've got a few tanks. I am almost certain they are all 68ci tanks. They are all almost exactly the same size. However... ...they have different cc values printed on them: 12.9cc 13.7cc 15.4cc ...using a cc to ci converter online, I get... 12.9cc = .787ci 13.7cc = .836ci 15.4cc = .940ci That is quite a spread. Why? Explain? Shives |

| Red=Moderator Join Date: Apr 2006 Location: Schen. NY | It has to do with REE (I noticed that in a tank sale... at least that's what the text looked like before the cc #) Anyone in the tank biz know what REE stands for? And darkstar.... you live in Jersey.. what would you know about CC  E

I will try and explain. When you test a tank, you fill it with water, screw it on a fitting with a HP hose and gets put into a water column (big steel pipe with a sealed lid, full of water). The water column has a small tube run out of it into a graduated container. A readin is taken with the water in the graduated container (in CC's), then the tank is pressurized to the proper pressure, (4500 for 3000 tanks, and IIRC 7000 for 4500) and the displacment of water in the water column is taken by the graduated beaker, and then pressure is let out. If the CC reading is more than the tanks rating (REE) it fails. If when it is depressurized it doesnt go back down to a certain percentage of the starting reading it fails. I think that is close to how its done, IIRC they used a container on a scale to accurately measure the amount of water displaced, but that part is kind of foggy in my melon...................
